Foldable Display with Multi-Angle Bending and Sliding Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable electronic devices are limited by their ability to be folded only in one direction, restricting usability and requiring a compromise between display size and portability.
Innovation Solution
A foldable electronic device design featuring a bending support part that can be bent at multiple angles, with sliding parts and a rail support part that allow for symmetrical sliding motions, enabling both in-folded and out-folded states while maintaining a compact form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display size is increased to provide a more pleasing user experience, then the display area is improved, but the device size increases and portability deteriorates
Solution Approach 1:
The display is divided into multiple segments that can be independently folded. The display structure includes first and second display areas that can be folded relative to each other, allowing the full display area to be large while the folded configuration maintains compact device size for portability.
Solution Approach 2:
The display structure is designed to nest within itself when folded. The first and second display areas are positioned such that they can be nested or folded close together, maximizing the display area when unfolded while minimizing the overall device volume when folded for portability.
2Adaptability or versatility
If the device is designed to be foldable in one direction, then the structure is simple, but the usability and flexibility are limited
Solution Approach 1:
The device is segmented into multiple foldable sections with first and second display areas that can be folded relative to each other. This segmentation enables folding in multiple directions while maintaining a manageable structural complexity through modular design.
Solution Approach 2:
The folding mechanism extends to multiple dimensions by allowing the first and second display areas to be folded relative to each other in different directions. This multi-dimensional folding capability enhances adaptability and versatility without requiring a completely complex structural redesign.
